C#  

public static Series WeightedMovingAverage( string seriesName, Series s, ElementValue elementValue, Series weightSeries, int lengthOfMA ) 
Parameters
 seriesName
 The name of the series which will be displayed on the chart, i.e. its label.
 s
 An series of historical values, where the first element corresponds to the market on the last period, the second term to the value on previous period and so on.
 elementValue
 Specifies the particular element value (for example High, Low, Close or Open of the financial time series) which will be considered within this indicator evaluation. In particular, if you wish to use the element value high then you should pass the parameter High. In a similarly fashion if you wish to use the low, close or open, then you should pass the parameter Low, Close, Open, respectively.
 weightSeries
 Array of doubles which assigns weights to the kth previous historical values for the given period on which the moving average is being evaluated. Here k is just the length of the weights array given.
 lengthOfMA
 The number of periods over which the weighted moving average is evaluated.
Return Value
A series where the first term is the value of the moving average corresponding of the latest period, the second term is the value for the previous period and so on.Exception  Description 

ArgumentException  Thrown if the length of the weights and series differ or if either series is empty. 
That is, the weights are fixed for all given historical values and the window of length
lengthOfMA
over which the GMA is evaluated is shifted along the series.
Application
Generally speaking the WMA where the weights are all set and the window over which GMA is evaluated is shifted is used when you wish to give emphasis to particular dates.
Note: The length of the weights
array must equal or be greater
than the length of the historicalPrices
series. If it's greater than we
ignore the supplementary values.
